Ravens in Fallout: New Vegas have distinctive black feathers. They are not considered an enemy, and will fly away if the player tries to get near it (approximately 10–15 feet). They can be killed if detected early enough, but there is no associated challenge for this other than Lord Death, I Dismember You, and a few others which are tied to any enemy. They will explode when shot, similar to how normal NPCs explode when killed when the player has the Bloody Mess perk.

This makes it possible to kill it with melee or unarmed weapons. [verified]

Releasing the aim button will fix this, and has not occurred when killing any other creatures or enemies in the game. [verified]
